Light Diffusion Masterbatch for PC
LD-MB510
The Seven Maters elaborately developed functional light diffusion masterbatch LD-MB510 is based on PC polymer matrix, coupled with Organic siloxane light diffusion microspheres. The LD-MB510 is better compatible with PC, easier to disperse in PC and have low volatility and good processibility. As a result, it is widely used in LED illumination, LCD panel and other PC optical materials. Such materials have wonderful appearance, combined with excellent light diffusion and light transparency characteristics.

Characters
• Better compatibility with PC and easier to disperse.
• Good thermal stability, suited to different kind of processing technology (injection and extrusion).
• Increase PC light diffusion rate remarkablely (>95%), meanwhile maintain transparency at high level (>80%).
• Improve impact strength of PC but do not have bad influence on strength.
• Improve processibility of PC.
• The PC products get different optical performances according to the different dosage of LD-MB510.
Recommended dosage
Extrusion: 5%-10%.
